Abstract

The invention discloses an automobile charging socket. The automobile charging socket includes a base having an inner cavity, a plurality of contact terminals are arranged in the inner cavity of the base, each contact terminal has an insertion hole used for insertion of a contact pin of charging equipment, and at least one circle of conductive wire which is used for contact with the contact pin and is in the shape of a spiral spring is arranged inside the insertion hole. The automobile charging socket provided by the invention adopts the conductive wire in the shape of a spiral spring to contact with the contact pin of the charging equipment for conduction, thus a contact area of the contact pin of the charging equipment and the conductive wire during charging can be greatly increased, contact resistance of the contact pin of the charging equipment is reduced, and a temperature rise is lowered. By adoption of the conductive wire in the shape of a spiral spring, the contact pin of the charging equipment and the conductive wire have a certain buffering effect, and thus the plugging and unplugging life of the contact pin can be greatly prolonged.

Description

technical field [0001] The invention relates to a charging socket, in particular to a charging socket for an electric vehicle. Background technique [0002] With the development of social economy and the further increase of energy demand, the voice of new energy technology is getting higher and higher. Electric vehicles are driven by power battery packs, and power battery packs need to be charged after power consumption. How to charge electric vehicles is an important issue. Charging piles or other charging equipment can effectively solve the problem of difficult charging. [0003] Crown springs, willow leaf springs or Radsok are currently used in similar electric vehicle charging sockets on the market. The defects of these contact conductive parts are that they have high contact resistance with the charging gun pins, high temperature and short life. Contents of the invention [0004] In order to solve the problems in the prior art, the present invention provides an auto...
